How DOEs spatial light modulator work?

Spatial light modulators (SLMs) are widely used as diffractive optical elements (DOEs) in optical systems to facilitate flexible control of light beams. In diffractive techniques, specific pattern is written onto the SLM by a computer and the input spatial light is modulated by the relevant pattern.

What are electro-optic modulators used for?

Some typical applications of electro-optic modulators are: modulating the power of a laser beam, e.g. for laser printing, high-speed digital data recording, or high-speed optical communications. in laser frequency stabilization schemes, e.g. with the Pound–Drever–Hall method.

Why is lithium niobate used as an electro-optic modulator?

However, Lithium Niobate modulators, based on the Pockels effect, offer several advantages, including, a purely linear electro-optic response, no free carrier absorption loss, a simpler fabrication process (no need for multiple ion implantations and anneals), and the highest bandwidths to date (>300 GHz [1]).
